Struct FuncState 

pub struct FuncState {

    pub f: Box<LuaProto>,
    pub prev: Option<Box<FuncState>>,
    pub bl: Option<Box<BlockCnt>>,
    pub pc: i32,
    pub lasttarget: i32,
    pub previousline: i32,
    pub nk: i32,
    pub np: i32,
    pub nabslineinfo: i32,

    pub needclose: bool,
    pub last_token_line: i32,
}

In C: stack-allocated in body(), chained via raw *prev pointer. In Rust: heap-allocated via Option<Box<FuncState>> in LexState.

Fields

f: Box<LuaProto>

PORT NOTE: types.tsv maps this to GcRef; we use Box during compilation to avoid RefCell overhead. close_func hands it to the GC/parent at close time.

prev: Option<Box<FuncState>>

bl: Option<Box<BlockCnt>>

pc: i32

lasttarget: i32

previousline: i32

nk: i32

np: i32

nabslineinfo: i32

firstlocal: i32

firstlabel: i32

ndebugvars: i16

nactvar: u8

nups: u8

freereg: u8

iwthabs: u8

needclose: bool

last_token_line: i32

Current ls.lastline value, mirrored on every sync_from_lex. Used by emit_inst to attribute the line to the just-consumed token (matching lua-c’s savelineinfo(fs, f, fs->ls->lastline)), instead of whatever line the caller threaded down. The threaded line param is preserved only for explicit overrides (luaK_fixline-style).

Trait Implementations

impl Debug for FuncState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
